I understand this game is all about the grind but I feel the catalysts might be the worst of it.
I mean, most of them have no guaranteed way of acquiring (specially the ones that drop on the glory playlist), depending a lot on RNG. And after you get one to drop you still need to get a million kills with the burn effect of the weapon or some other absurd requirement.
My point is, all catalysts should have a guaranteed way of dropping, or even better, they should already come with the weapon!! Crazy idea, I know, but then you could just choose which weapons you want to masterwork, and would still need to get all the kills or whatever they ask you to do.
